A Rush to Innovate Silicon Solar Technology

A Rush to Innovate Silicon Solar Technology

Turns out, a lot more can be done to chip away at the manufacturing cost. This is especially true when silicon technology companies are eager to set their products apart in a market that’s got way too many same-same solar panels. “There is a real sense now that the crystalline silicon process flow, which has been fairly mature and undifferentiated, is headed for a change,” said Shyam Mehta, senior analyst at GTM Research, during a webinar on the photovoltaic market outlook on Tuesday. Mehta rattled off some of the technologies that are being developed or employed: select emitters, cast monocrystalline ingot, backside passivation. Silicon wafers will become thinner than the 200-micron variety that is commonly used today. All these technologies are meant to reduce material costs and improve the amount of sunlight that solar cells can convert to electricity. It’s not as if so...
